This tests multi-source data unification and identity resolution. A strong answer covers ID stitching, a unified profile, deterministic or ML segmentation, and data quality. RED FLAG: Treating email as a perfect join key or ignoring anonymous users.

A strong answer covers deterministic and probabilistic ID stitching, a unified profile merging behavioral and firmographic attributes, deterministic or ML-driven segmentation rules for personas, and robust handling of schema drift and data freshness. RED FLAG: Proposing a simple SQL join on email without addressing anonymous users, data quality issues, or merge conflict resolution.
